P2P systems have shown useful to many types of distributed systems due to their features of efficient direct communication among peers. Although initially motivated by the need for efficient file sharing among large amount of peers, P2P techniques have found wide applicability to many domains within large scale distributed systems such as solving complex problems from science and engineering, data...
Mobile ad-hoc networks (MANETs) are autonomous distributed networks, where mobile nodes communicate with each other using wireless links. Since the communication is done by wireless links, it is difficult to grasp the network situation. It becomes even more difficult when the number of nodes is increased. In this paper, we propose a visualization system for MANETs. The system can mainly visualize...
This paper investigates into the transaction management of mobile web services, which is crucial to maintaining execution correctness of services and consistency of their underlying data. We propose a relaxed set of transaction correctness criteria, called Sacred (Semantic Atomicity, Consistency, Resiliency, Durability) and design protocols for enforcing these criteria in the execution of transactions...
In Mobile Ad-hoc Networks (MANETs) mobility and the absence of any fixed infrastructure brings attractiveness for its usage in time-critical applications and indoor environments. In this paper, we investigate the performance of our MANET test bed in indoor stairs scenarios. We analyze the behavior of Better Approach To Mobile Ad-hoc Network (BATMAN), considering two metrics: throughput and packet...
Event detection is a major issue for applications of wireless sensor networks. In order to detect an event, a sensor network has to identify which application-specific incident has occurred based on the raw data gathered by individual sensor nodes. Sensor networks are a sensing, computing and communication infrastructure that are able to observe and respond to phenomena in the natural environment...
